This invention relates to'weaving'and has 4 particular reference to handlooms.

Among the objects of the invention is to provide a hand loomparticularly designed or constructed for rapid and satisfactory use rkpositioned upon a table, desk or the More definitely stated I provide bythis new mechanism a loonffso constructed that the beater even-though itconstitutes'apart of a machine which as a whole occupies a minimumamount of Vertical space above the table or other support, yet may beoperated for beating purposes through a wide space with respect to thelongitudinal-movement of the fabric that is being woven. In other wordswhile the beater in machines commonly in use supported upon the floorhas a pivotal or swinging movement from the axis adjacent to the floorin order to provide the proper amount 'of throw or movement of thebeater it is obvious that the same amount of throw cannot beaccomplished in a loom of the type herein indicated when pivotalmovement alone is depended upon.

Another object of the invention is to provide im roved facilities formanipulating the hed le frame providin for an easy means for lifting theheddle ame and holding it in lifted position while both of the operatorshands are free for the purpose of adjusting the weft threads or otherpurposes. I

A still further object of the invention is to provide a means for lockinthe heddle frame in any desired position with sufficient firmness tohold the two sets of warp threads in any desired relation to each other.

Another object of the invention is to provide a relatively small andcheap loom con- 'struction, one that will occupy a minimum amount ofspace either in use or stored away,- and which yet has a large capacity.for actual service and one which enables the operator to weave arelatively long portion' of cloth 'without readjustment of the warp andcloth.

Fig. 6 is a small diagram indicating my loom supported upon a table'andhaving a treadle to. manipulate the heddle frame connections. Referringnow more particularly to the drawings, I show a loom comprising rightand left panels 10 'and ll indicated as occu- I I and illustrating incomparison with Fig. 3 the combined sliding pying parallel verticalplanes and connected by transverse horizontal front and rear frame bars12 and 13 respectively having any suitable supporting feet. 1 1 servingto support the machine upona table or other analogous elevated supportas distinguished purpose of facilitating access of the operators handsto the work being performed.

In the otherwise open front end of the frame are secured the cloth beam17 close above the bar 12, and the breast beam 18 above the cloth beam.At the rear end of the frame and pp r ed between the rear -construct1 0ndisclosed or suggested herein, I

I The two sets of Warp of guides secured upon the inner face of eachside panel.

. 26 indicates a rock shaft ournaled 1n and' J ter of its length therock betwe'enthe two side panels at the rear of the heddle frame andbelow the warp. At any convenient place, preferably at the censhaft isprovided with a lever 27 which projects forward normally because of theaction of springs 27 anchored at one end to the upper rear portion ofthe shaft and at the other end to the rear cross bar 13 and tending torotate the rock shaft in a clock-wise direction as viewed in Fig. 3.Near its ends the rock shaft is provided with a pair of arms 28 whichare arranged approximately at an angle of 90 degrees from the plane ofthe lever 27 and hence which project normally upward from the rockshaft. The outer ends of the arms 28 are bent at an angle or parallel tothe axis of the rock shaft and havesliding engagement in the slots ofapair of bars-29' pivoted at 29 at their front ends to the ends of theheddle frame, while the rear portionsof the slotted bars have pivotaland sliding movement overfixed studs or pivots 29 secured to the innersurfaces of the. rear ends of the side plates 10 and 11. It will thus beseen that the force of the springs 27 will act or tend to act to rotatethe rock shaft and its arms 28 to lift the heddle frame into the dottedline position of Fig. 3 forming an upper shed.

Any suitable means may. be provided to manipulate the rock shaft inacounter clockwise direction against the force of the springs 27 to lowerthe heddle frame and make a lower shed'as shown in full lines in Fig.3.To this end I provide a flexible connection 30 leading from the free endof the lever- 27 rearwardv over a guide pulley 31v and thence forwardover another pulley 32. This cord may be manipulated either by hand asapplied to a handle 33, Figs. 2- and 3, or by means of a treadle 33',Fig. 6, when it is convenient foot. It is to be noted in this connectionthat the means for manipulating the heddle frame may be practiced by anoperator who has lost either a foot ora hand. When the treadle is usedthe heddle frame may be' held down by the pressure of the foot on thetreadle, but when the hand is used for rection toward and from theoperator.

for the operator to use her.

drawing the heddle frame downward the heddle frame may be held orpreferably the connection 30 may be snubbed temporarily a over afastener 34 of any convenient construction. Furthermore by the meansjust described, or their equivalent, the heddle frame may be held at anyposition intermediate of its uppermost and lowermost positions,'anexpedient frequently useful in the application of ornamental features tothe work or for other purposes.

The readers attention is now called to the beater 37 comprising two mainparts, the

upright frame carrying a reed 38 and a base comprising a horizontal bar39, and a pair of shoes 40 at opposite ends of the bar movable alongguideways 41 at the bottom edges of the side panels 10 and 11. Withrespect then to these guideways 41 the-beater as a whole 'is movablebodily in a horizontal di- The reed frame, however, is hinged at 42- tothe base, the hinges being indicated as secured to the lower end of thereed frame posts 43 and the ends of the base bar 39, hence the reedportion of the beater with respect to the axis of the hinges 42 isadapted to swing forward especially during the .latter part of themovement of the beater in a manner somewhat similar to the usual beateraction. A pair of springs 44 are connected to the reed frame and therear ends of the shoes 40, these springs having the function to tend tohold the reed frame upright, the rearward tilt of the reed frame underthe force 'of the springs being limited to the vertical by reason of theframe striking against the upper part of the bar 39. Though the spacebetween the breast beam 18 and the heddle frame 23 may be relativelydeep or long, I am able to secure practically every advantage of thepivoted beater of the floor machine as well as maximum "length of thework without readjustment even though the machine occupies a relativelyslight vertical space. To this end the'action is approximately asfollows: With the beater frame area left free it is held upward by thesprings 44 and-the operator pushing rearwardthereon moves the entirebeater along the guideways 41 with practically the same facility andfreedomaS the ordinary beater is moved rearward around the axis near thefloor. This position then of the beater would be somewhat to the rear ofthat indicated in Fig. 3 giving. a maximum shed. After adjustment of theweft the operator grasps the top of'the beater and draws it bodilyforward, the base gliding easily along the guideways 41 as far asdesired. The operator then completes the movement of the beater bydrawing downward upon the top thereof as shown in Fig. 5 against theforce of the springs 44 which produces a true beating action. While inpractice I recommend a relatively slow or gentle movement of the beateras "distinguished from a powerful blow or impact, still I have foundthat the pivotal movement of the beater will produce a more uniformresult than if a slidable movement only were depended upon. .The

shoes of the-base are ofsuch a length and the other parts of the beaterare so related thereto that'the beater may be moved to and fro withoutcramping or material resistance without tilting or bending at thehinges,- but when the final pivotal movement is desired the shoes havesufficient length in the guideways to hold the base from further slidingmovement when the top of the beater frame and horizontal guides formedtherein, a ver-v tically movable heddle frame guidedin one pair of theframe guides, and a heater comprising a base slidable in the other pairof guides and a reed portion pivoted to the base, 2.
